i agree with coelho about the color thing, infact its a thought that ive had floating around, and have tried to explain whilst high, and failed, and tried to explain while sober, and failed, and decided i will continue to think it. I agree i mean, i see a color ive been told is blue, and you see the same object, and call it blue, but who says what i consider blue if i were you would look like what blue looks like to me, what if your blue was my purple, we will never know, and the attempts to use science in the form of the radioactive spectrum doesnt work because the colors still look that way to you, and youve associated the name of that color to the color that you see, and accept that the world looks that way. As far as anyone knows, when i see the world it is really inverted from you, but i still call the sun yellow, and the grass green.
